Like any good power couple, Spiegel and Kerr purportedly share interests in each others' endeavors. He's graced the cover of Vogue Italy, and she's active on Snapchat and has come to the defense of the company— and her husband — in interviews.

Here's how the newlyweds spend their billions.

Spiegel and Kerr began dating during the summer of 2015 after first meeting at a dinner for Louis Vuitton the year before.

In July 2016, Spiegel proposed to Kerr with a a 1.75 to 2.5 carat diamond that cost an estimated $75,000 to $100,000.

A few months before the engagement, the couple purchased a 7,164-square-foot home in Brentwood, a wealthy Los Angeles neighborhood, for $12 million. The home was previously owned by Harrison Ford and has a gym, pool, and guest house.

Kerr also owns a four-bedroom ocean view home in Malibu, which she bought in 2014 for $2.15 million. She's made the home eco-friendly with help from Spiegel, who reportedly gifted her a machine that produces sustainable water for the entire house.

In May 2017, the couple held their wedding ceremony and reception under a canopy in the backyard of their Brentwood estate. It was an intimate affair complete with pre-nuptial yoga, a slow-roasted chicken dish for dinner, and after-hours karaoke. Kerr's Christian Dior Couture wedding dress was custom-made.

Spiegel and Kerr reportedly honeymooned on the private island of Laucala in Fiji at a resort owned by Red Bull billionaire Dietrich Mateschitz. The nightly rate for one of the 25 villas on site is between $6,000 and $60,000. With a minimum stay of four nights, the couple dropped at least $24,000 on honeymoon accommodations, though some sources say they may have stayed in the owner's private home.

Shortly after Snap went public and Spiegel and Kerr tied the knot, the CEO reportedly took some time off for a "bro trip" sailing off the coast of Italy and Greece in a megayacht that rents for $967,415 a week.

But Spiegel ultimately prefers land over sea. "Cars bring me sheer joy," a then 16-year-old Spiegel wrote in a 2008 letter to his parents asking them to lease him a BMW 550i, which retails for about $75,000. After Snapchat completed a big funding round in June 2015, he bought himself a Ferrari.

Though Spiegel is more fashion forward than most tech CEOs — he appeared on the cover of Vogue Italy in 2015 — he still wears a classic uniform of a $60 James Perse white v-neck, $255 Patrik Ervell black jeans, and $463 Common Projects sneakers.

The couple doesn't appear to have expensive hobbies. Kerr says Spiegel loves to come home and chill with the family. "He's 25, but he acts like he's 50. He's not out partying," Kerr once said. "He goes to work in Venice [Beach, in LA]. He comes home. We don't go out. We'd rather be at home and have dinner, go to bed early."
